At the recent Service Learning & Volunteering STEM EXPO 2020, held virtually in Portland, Maine, Cornerstones of Science was excited and honored to showcase its Rev Up the Fun project of online science activities and associated videos. This year’s STEM EXPO offered a wide range of presenters and exhibitions for students in grades K-12 who are passionate about STEM. As an added inspiration, the president of EnviroLogix, a global leader in the development of STEM technology, gave a keynote speech, as well as the Dean of the College of Science, Technology, and Health at the University of Southern Maine, and the Superintendent of Portland Public Schools. Their message? STEM leads to great jobs!

Because of its reputation for exceptional STEM learning resources, Cornerstones of Science was invited to showcase a brand-new activity called Flip the Switch, designed in collaboration with Maine Campus Compact through a Maine Department of Environmental Stewardship program. Flip the Switch is designed to inspire and excite K-4th grade students about energy conservation. An entertaining 3-minute video, shown below and hosted by two engaging Maine AmeriCorps volunteers, accompanies the activity and explains not only why conserving energy matters but shows youngsters how to follow an easy checklist that can make a big difference at home.


The video and a helpful activity sheet are also available on the Rev Up The Fun website, along with more energy conservation activities, as well as fun health- and space-related activities . was developed by Cornerstones of Science in the summer of 2020 to pivot from in-person science activities to science activities that can be done at home with common household items.

Best of all? These programs are free and available to anyone, anytime.
